Intermittent screen shut off

[SemperFitz]

Hi All,

As the the title says, the screen goes to black but the PC stays on. Turn the PC off for a while and the screen is back.

Graphics problem or heating?

TIA

Unfortunately no other monitor. If it was monitor though i wouldn't see the 'No Signal' message which i do see when it happens.

Graphics card is AMD Radeon HD 7700 Series. Old, so my thoughts are graphics related.
